The ProMag PM089A Magazine Spacer is engineered to facilitate the integration of full-size Glock 17 and Glock 22 magazines with Glock 26 and Glock 27 compact pistol frames. This accessory is precision-designed to bridge the interface between the compact frame and the extended magazine’s baseplate, establishing a complete and consistent grip profile.
Key Features
Integrated Fit
Constructed from durable, injection-molded polymer, the PM089A features a textured surface engineered to match the existing Glock pistol frame. This design optimizes the interface, ensuring a cohesive feel and preventing significant ergonomic disruption.
Secure Attachment
The spacer integrates securely onto the magazine via a single Allen-head cap-screw. This attachment method ensures robust retention and stability, mitigating movement during high-stress operations or dynamic reloads.
Enhanced Ergonomics
By extending the grip surface when utilizing longer magazines, this spacer significantly improves weapon handling and control. This ergonomic enhancement is particularly beneficial during sustained firing sequences, competitive engagements, or rapid magazine changes, providing a full-hand grip on compact platforms.
This magazine spacer represents a pragmatic enhancement for Glock 26 and 27 owners. It provides the operational versatility to leverage readily available full-size magazines, increasing ammunition capacity for training, competitive use, or as a support component for personal defense firearms. It integrates as a reliable accessory, augmenting the functional parameters of concealed carry pistol platforms. Important Note: This spacer is specifically engineered for Glock Gen 1-3 pistol frames and is not compatible with Gen 4 Glock pistol frames.
